When

{CH}_3 {COOCH}_3+{HCl}

is titrated with

{NaOH}

then at netural point the colour of phenolphthalein becomes colourless from pink

View answer and explanation

Correct option: B

Due to formation of

{CH}_3 {COOH}

which acts as a weak acid.

The correct answer is B (Due to formation of CH₃COOH which acts as a weak acid) because the hydrolysis of methyl acetate produces acetic acid, which neutralizes the NaOH, causing the phenolphthalein to become colorless at the endpoint.
